5.2 Wind Suspension Rate Calculations

 This section deals specifically with wind suspension emissions calculations.  Volatilization as a release mechanism is discussed in Section 5.4.4.

 The release of contaminants into the atmosphere is often a function of local conditions.  Important factors can be temperature, moisture, wind speed, surface characteristics (e.g., crust formation, roughness, or vegetation cover), the physical state and chemical form of the contaminant (e.g., gas or particulate, reactive or nonreactive), and location of the contaminant (i.e., on the surface, buried under a soil layer, immobilized by in-situ treatments, or containerized).
